Review on 09 08 240 SBA Ultra High by Roger King

I already knew that the Knipex is one of the best pliers. My review just focuses on the question: How many megohms of insulation resistance (IR) am I really getting with a pair of pliers advertised as insulated versus a pair of pliers advertised as not so but with a soft grip? Since I own an insulation resistance meter, Hioki IR4057-20, I decided to do a little DIY test. It turns out that with such pliers you really get what you pay for in IR. In this quick experiment, I took measurements with insulated Knipex tongs, a cheap insulated tong I call "Tong 2" and a Klein-glow tong (insulated not advertised). The test voltage was 1000 volts DC. As for the quality of the small tongs, I'm pretty sure if I had the insulated version it would be just as good as the others. Anyway, this is for reference only. Knipex insulated pliers: 4000 MΩ (value at the end of the scale on my measuring device) Tong 2 insulated: 4000 MΩ (value at the end of the scale on my measuring device) Klein Glow non-insulated pliers: 862 MΩ (not bad) Even in the thinnest insulating part, Knipex registered a stable 4000 MΩ.
